FROM THIS EPISODE

Nine young people brought to the US illegally as children voluntarily crossed the Mexican border. When they asked re-entry to the country where they've been raised if not born, they were placed in detention. We update the actions — and the risks — taken by so-called "Dreamers" who've become political activists. Also, investigation of how sexual assault cases are handled by USC and new details on how the LA Sheriff's department hid a federal informant from the FBI.

On our rebroadcast of today's To the Point, since the George Zimmerman verdict, polls show a sharp divide between blacks and whites when it comes to the justice system. President Obama has tried to explain why blacks are so angry. Will another "national conversation" make things better or worse?

In 2011, convicted bank robber Anthony Brown was in LA County jail awaiting transfer to federal prison. Sheriff's deputies discovered he had a contraband cell phone with a record of calls to the FBI. The feds were investigating charges of jail-house brutality. The Sheriff's Department then launched Operation Pandora's Box. Celeste Fremon, who blogs at Witness LA, has published new details of "elaborate lengths to hide a federal informant from the FBI."

In April, students and faculty at Occidental College filed federal complaints about campus handling of rape and sexual assault cases. Now they're working with women at USC, and the US Department of Education is investigating. Danielle Dirks is Assistant Professor of Sociology at Occidental.

Nine young people — raised but not born in the United States — are being held in detention in Arizona. Frustrated by the failure of the so-called "DREAM Act" to grant them citizenship and unsatisfied by President Obama's offer of deferred deportation, they crossed into Mexico and then asked for the right to return on humanitarian grounds. Lizbeth Mateo, who was 10 when she was brought to the US, is a graduate of Cal State Northridge who's already told Santa Clara Law School she may not make classes on time. Before crossing the border, she made a video statement.
